Abstract
A sound generator includes a memory bank storing user-selectable recorded sounds, a microprocessor that can quasi-randomly time-delay at least one of the recorded sounds, and a mixer that can combine a user-selected recorded sound and the time-delayed sound for output by speakers or earphones. The microprocessor can also cause the output sound to include a microprocessor-selected one of the recorded sounds for inclusion during playback of a user-recorded sound.
